The discovery implies the Nephila could be one of the longest genus of spider known.

The fossil, discovered in Daohugou, China, measures about two inches across. That might not sound giant, but researchers say the implications are huge.

“This giant fossil orb-weaver provides evidence of predation on medium to large insects, well known from the Daohugou beds, and would have played an important role in the evolution of these insects,” according to researchers.

The modern Nephila are commonly known as golden orb spiders, which can grow as large as five inches. They’re usually found in tropical climates, meaning ancient Daohugou was likely warm.
